But the micronutrient selection is only relevant if you only consume Soylent, and most people here seem to be saying that they only consume some Soylent products in replacement of a couple of meals/when they don't have time. So if the rest of your meals are normal meals you will have filled your micronutrients requirements already. Soylent is only beneficial then over a protein bar if you plan to eat garbage the rest of the day too, but then if you do the macronutrient profile of Soylent becomes pointless, because the garbage you are going to eat later on is probably going to be carbs and fat bombs (as garbage food usually is).
Therefore I don't really see the place that Soylent is trying to occupy and I can't help but dismiss it as another nutritional fad.

Granted, they are trying to do different things; Soylent tastes like crap but has a lot of nutrients(supposedly a "complete" meal), whereas Quest is higher in protein and lower in sugar while tasting terrific.
Personally, I would still choose Quest over Soylent because I suspect that the idea that we need a constant intake of a wide variety of nutrients isn't really true. I'm not denying that we definitely need vitamins and minerals, but experience of going months eating very few vegetables(and almost entirely meat and cheese) has caused no noticeable health effects in me besides weight loss. We're made to think that we've got to eat a ton of vegetables and even take supplements, which I think might be more clever marketing than anything else.
